摘要
我国西南山区有着丰富的水利资源,随着水资源的开发和水利工程建设的加快,库区公路复建工程也越来越多,这类复建工程往往具有较高的桥隧比。库区桥梁具备山区桥梁建设的典型特点,如山高、谷深、坡陡、弯急、地质条件差、地震影响大、不良地质类型多等,此外,还具有水位落差大、库岸再造频繁、通航及景观需求高等特点。论文总结了库区桥梁设计的基本原则,结合项目实际情况优化了典型上、下部结构选择,并列举了几处重要工点的桥型设计,希望能为类似工程提供参考。
There are abundant water resources in the mountainous areas of southwest China.With the development of water resources and the acceleration of water conservancy construction,there are more and more highway reconstruction projects in the reservoir area,which often have a high bridge-tunnel ratio.Bridges in the reservoir area have the typical characteristics of mountain bridges,such as high mountains,deep valleys,steep slopes,sharp bends,poor geological conditions,great earthquake influence,many unfavorable geological types,etc..Besides,they also have the characteristics of large water level drop,frequent reconstruction of reservoir banks,high navigation and landscape requirements,etc..This paper summarizes the basic principles of bridge design in the reservoir area,optimizes the selection of typical superstructure and substructure according to the actual situation of the project,and lists the bridge type design of several important construction sites,hoping to provide reference for similar projects.
